  • Step 1


In your specific case, given the current state, try


diskutil eraseVolume jhfs+ BC1 disk0s3


diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list


  • Step 2


If you see only disk0s3 as the last entry under disk0, then run


diskutil eraseVolume fat32 BOOTCAMP disk0s3


and retry removing the partition using BC Assistant only.


Once disk space is back in the main APFS Container, run SMC and NVRAM Reset and try to install Windows. Post any error messages, you see.
